Don't mess! Michael Phelps didn't just scream and holler after beating his rival Chad le Clos at the 2016 Rio Olympics on Tuesday, August 9. The athlete also threw in a little finger wag.
Phelps, 31, beat the defending champion South African swimmer, 24, and everyone else, during the 200m butterfly event. To celebrate, he threw his arms up in the air and shook his finger back and forth at the crowd. Le Clos previously beat Phelps in the same match at the London Games in 2012.

The win got Phelps his 20th gold medal. Later on, he earned his 21st gold after winning the men's 4x200 meter freestyle relay with teammates Ryan Lochte, Conor Dwyer and Townley Haas.

One day earlier, Phelps appeared annoyed at le Clos when he shadowboxed in front of Phelps before another competition. The distraction led Phelps to give a hilarious mean mug, which quickly went viral with the hashtag #PhelpsFace.

Le Clos hasn't been one to keep quiet about Phelps. "[Phelps] has been talking a lot of smack in the media about how slow the butterfly is, so I just can’t wait until I race him," he previously told reporters, via Fox News. "I just did a time that he hasn’t done in four years, so he can keep quiet now."

Despite the rivalry, the men hugged in the water following the 200m butterfly on Tuesday night. Phelps went on to collect his medals and got choked up on the podium as America's national anthem, "The Star Spangled Banner," played in the background.
